Often there is some problem in ordinary cable production, how to resolve these problem very important for finished cable quality.
Cable making problem , reason and resolution：
（1）All plasticization is not good (surface is powdery, dull and matt)
Extruder barrel (screw) temperature not enough
Appropriately increase extruder barrel (screw) temperature.
(2）Part plasticization is not good (the surface is not smooth, like orange peel)
Screw LD small or screw rotational speed too fast
Lower the screw rotational speed.
(3) Bad seam
Crosshead temperature not enough or barrel temperature too high, the material viscosity is small, the pressure is insufficient.
Appropriately increase crosshead temperature or lower barrel temperature.
(4) Foaming, old plastic and particles
Extruder barrel or crosshead temperature too high, or there is material in gap or dead corner of crosshead or extruder screw.
Appropriate lower barrel or crosshead temperature, clean crosshead and screw.
(5) Air bubble
Extruder barrel or crosshead temperature too high cause the material overheat decomposition, precipitation of gas, or material is wet or use wrong material.
Adjust temperature, clean crosshead, change material or dry material first.
